And the second sliding spool of the first sliding spool are interlockingly connected to each other, and the first link is selectively engaged with the interlocking member of the balance link and the first sliding spool and the interlocking member of the balance link and the second sliding spool. A fixing tool is provided to stop the first and second sliding spools from sliding selectively. And
When the operating tool is operated while the fixing tool is acting on the second spool side, the balance link swings around the connecting shaft core of the second spool side interlocking member, and the first sliding spool operates to operate the first sliding spool. When the control valve is switched and the operating tool is operated while the fixing tool is acting on the first spool side, the balance link swings around the connecting shaft core of the first spool side interlocking member, and
